Amazon Custom Software Needed

My company needs a custom made Amazon software program. We are sellers on [url removed, login to view] and we need a tool that interacts with [url removed, login to view] via a desktop application. The program needs to be able to check and compare prices of a batch of items, upload/download inventory, download and manage orders and a few more specific functions. A similar program called SellerEngine ([url removed, login to view]) already exists, but it does not fulfill our particular needs. Nevertheless, check it out as a reference because what we need would be something similar. We would like a programmer that preferably has had some experience with Amazon Web Services and VBA are required for the, but I assume you may need more to successfully complete the project. I need this done relatively soon. Although quality of work is more important than the time frame, I would like to have the project completed as soon as possible. Keep in mind that if you are not familiar with AWS (Amazon Web Services)
